(a) The difference in AB levels (ng/mL) between all participants at 6 months after the second dose and the Non COVID-19 and COVID-19 groups at 6 months after the third dose. D2M6_All = all participants at 6 months after the second dose; D3M6_NC = participants who did not contract SARS-CoV-2 within 6 months after the third dose; D3M6_C = participants who contracted SARS-CoV-2 within 6 months after the booster dose. (b) The difference in AB levels between the NC2 group (subjects not infected) 4 months after the third dose and the C2 group (subjects who became infected within 2 months of the third dose) 4 months after the infection. Asterisks indicate significant differences ** = p < 0.05.
